  2. Sunset (color) - Wikipedia

    en.wikipedia.org/wiki/Sunset_(color)

    Because the shorter wavelength components, such as blue and green, scatter more strongly, these colors are preferentially removed from the beam. [2] At sunrise and sunset, when the path through the atmosphere is longer, the blue and green components are removed almost completely, leaving the longer wavelength orange and red hues we see at those ...

    The colors of the Martian sunset differ from those on Earth. Mars has a thin atmosphere , lacking oxygen and nitrogen , so the light scattering is not dominated by a Rayleigh Scattering process. Instead, the air is full of red dust , blown into the atmosphere by high winds, [ 22 ] so its sky color is mainly determined by a Mie Scattering ...

    [9] [10] [12] [15] Ash from volcanic eruptions, trapped within the troposphere, tends to mute sunset and sunrise colors, while volcanic ejecta that is instead lofted into the stratosphere (as thin clouds of tiny sulfuric acid droplets), can yield beautiful post-sunset colors called afterglows and pre-sunrise glows.

    The Belt of Venus – also called Venus's Girdle, the antitwilight arch, or antitwilight [1] – is an atmospheric phenomenon visible shortly before sunrise or after sunset, during civil twilight. It is a pinkish glow that surrounds the observer, extending roughly 10–20° above the horizon .

    The yellow color is due to the presence of pollutants in the smoke. Yellowish clouds caused by the presence of nitrogen dioxide are sometimes seen in urban areas with high air pollution levels. [22] Red, orange and pink clouds occur almost entirely at sunrise and sunset and are the result of the scattering of sunlight by the atmosphere.

    Purple results when weak rays of light mix with something light and shady, such as at sunrise or sunset when weak rays of light hit the air that is trying to darken. Pseudo-Aristotle, de Coloribus 2.1 [2] Aristotle theorizes that simple colors are the result of mixtures between varying levels of light and either black or white.
